Although these elements are known to be derivations that express the values: small, big, bad, good; there are many EVs features neglected by common definitions. EVs can sometimes fulfill two different functions at the same time and even become part of the grammar of a language. How and ... [Show full abstract] what material EVs evolve from, decides how they are later embedded in a grammar. Three of those processes are illustrated in the development of EVs in three unrelated languages through which Evaluative morphology could be subdivided in at least three different types.
